Question

The inverse transformation from s back to r is denoted as:

(a) s=T^-1(r) for 0≤s≤1

(b) r=T^-1(s) for 0≤r≤1

(c) r=T^-1(s) for 0≤s≤1

(d) r=T^-1(s) for 0≥s≥1

The question was asked in an online interview.

My question is taken from Histogram Processing in portion Intensity Transformations and Spatial Filtering of Digital Image Processing

Answer 1

Right answer is (c) r=T^-1(s) for 0≤s≤1

The best explanation: The inverse transformation from s back to r is denoted by:

r=T-1(s) for 0≤s≤1.
